Oxytocin (pitocin) is a drug commonly used in obstetric practice, and the drug effect is to increase the muscular tone of the uterus to reduce uterine bleeding after neonatal delivery. Pregnant patients undergoing elective (scheduled)Cesarean delivery routinely receive oxytocin after delivery of the baby. Post-delivery, oxytocin is commonly administered as an IV bolus and/or infusion. No previous studies have accurately assessed differences in oxytocin infusions after delivery in patients undergoing elective cesarean delivery. Thus the study aim is to investigate which infusion rate can optimally provide adequate maintenance of uterine tone during Cesarean delivery while being associated with minimal or no maternal side-effects.
